Possibly. You can plant them now that temperatures are starting to cool down. Remember to maintain the soil moist and mulch with at least 3-4" of any type of acidic soil.

You did not mention the name of the variety so I cautioned just in case your variety cannot handle your Zone 7 winters. If it cannot be planted in your zone then I suggest you keep it in a pot outside during the growing season. Then bring it inside during winter (as soon as the temperatures go below freezing and the plant becomes dormant). Place it in a garage but remember to water it (less than usual but still some) while in the garage. Potting soil can dry easily.
